About
Keygrain generates unique passwords on your device — no vault, no database that hackers can target. Unlike traditional password managers, there is no encrypted vault that can be breached. ## FEATURES: • No vault — passwords are generated on-demand, never stored • Autofill — Ctrl+Shift+K or right-click to fill credentials • TOTP — generate 2FA codes without a separate authenticator app • Encrypted sync — sync across all your devices (end-to-end encrypted) • Per-site settings — customize password length, symbols, and rotation • PIN lock — quick access without retyping your master password • Auto-lock — clears secret from memory after inactivity • Visual fingerprint — colored dots confirm your master password is correct • Works offline — no internet needed to generate passwords • SSH keys and crypto wallets (for developers) • Import — migrate from other password managers via CSV export ## HOW IT WORKS: Enter your master password and email once. Keygrain uses memory-hard key stretching (Argon2id) to derive a unique password for any site. Same inputs, same password — every time, on every device. ## SYNC: Your service list is encrypted before it leaves your device. The server stores only encrypted data and cannot read your passwords. Self-host the sync server or use keygrain.com. ## PRIVACY: • Master password never stored or transmitted • No analytics, no tracking, no telemetry • No account creation required • Open source: https://dev.secbytech.com/opensource/keygrain Also available: Android app and web generator (keygrain.com/generate — try before installing).
